This invention relates to an improved indicia stamping device, particularly for num-' bering metal constructions such as vehicle chassis frames. 7 I g The main objects of the invention are to provide a portable device of, this kind of light Construction which, when in use-,. is supported; upon the 3 structure to which the indicia is beingiapplied; toprovide an imroved stamping device which may be applied to both fiat and angular metal bars of various sizes after the latter have been assembled in a substantially complete structure; to provide a manually operable stamp letter or figure 0 a series of numbers, letters or figures is independently held in place and applied under substantial pressure by a cam action; toprovide stamping devicewhichhas a work support having stationary engagement with t of said cams work for resisting the pressure 4 work and to provide means for adapting the support so as tq condition the stamping stocks of various thicknesses.

A11 illustrative embodiment of this invention is shown in the accompanying drawings, in which: I y -'j I Fig. 1 is a front elevation of an indicia stamping device, partly in section. a v I Fig. 2 is a top plan view of thestamping device shown in Fig. 1. y I 1 Fig. 3 is a horizontal section takenon line 8-3 of Fig.1.- I r .4 Fig. 4 is a fragmentary, enlarged, vertical section taken on line 4-4 of Fig. 2.

In the form shown, the improved stamping device includes a swingable body part 1 of T-shaped cross section which'has a hearing 2 atone end and an eye 3;at the other end. A work supporting arm 4 having a pivot 5 journaled in the bearing 2 is located at the left end of the body part or link 1 and is provided with a demountable work engag-.

ing jaw 6 which is secured on the extremity of the arm 4 by bolts heads 8. The pivot 5 of the arm 4 is secured against displacement from the bearing 2 by a washer 9 and a nut 10 which is threaded on the reduced outer end 11 of the pivot 5. The end 11 has an integral upright stem 12 f with a handle and it has a relatively thin extension 20' on its opposite end having an device for plate 22 7 having countersunk 1930. Serial rim-450,823..

which is provided a cross pin by which the arm 4 may beconveniently rotated relative to the link 1. The. pivot 5; liasan ar cuate slot 14 in its periphery into which a pin15 threaded in the bearing 2 extends for limiting relative rotation ofthe-link 1 and A bolt-16 mountedwin the eye3vhas a 230111?- nal part 17 on which a member 18 having an arcuate end portion is rotatably supported;

The boltlfi is secured against rotation re1a-- tive to the eye 3 by a key 15 which-extendsinto a key-way 16 in the inner periphery of the eye. 'The member is provided on .oneend arcuate face 31 on its extremity. iMounted onthe respectively opposite sides of the proection 20' are plates 22. and 23whic-h extend.

' in advance of the arcuate face 21 and have,

spaced, inwardly; projecting. registering lugs 24 and 25 respectively forming a seriesof'ad-v V acent sockets in which pieces of type on other embossing elements 26 are seated.-

y The inner ends of the type 26 engage the arcuate face 21 and as the type are of the same-height, the outer or embossingends thereof are arranged on a curve which correspondswith the curvature of the face 21. Formed in the outer edge portion ofthe at their inner ends with the sockets in which the type 26 are mounted. Each aperture 27 has a constricted inner end'in whicha ball 28 is located and the outerends of the apertures are closed by a threaded plugi29. A spring 30 bears between the plug 29, and the ball- 28 ing the latter in place.

side of the type26,1thereby removably secur- 8'0 are apertures 27 wlnch commumcate I 'so as to yieldably'urge the latter againstthe,

1 In 0 eration the stamping device 1s ma 1 side of the web of the bar. The member 18 is then rocked relative to the link 1 and work supporting arm 4 by manipulation of the handle 19. This rocking action brings successive pieces of type into embossing engagement with the other side of the web, the curvature of the arcuate face 21 allowing the 31 during swinging of the link 1 in oscillatype to have rolling engagement with the ban tion of the member 18.

It is understood that the stamping device may be used on flat pieces of workas well as in channel and angle shaped members, in which case the body part 1 would restupon the edge of the work thereby predetermining the distance from the edge thereof at which the type 26 are applied. I

The device may be advantageously used in numbering vehicle frames for the spring pressed detents permit'any one of a series of pieces of type to be conveniently removed and replaced. The entire device is light in Weight and capable of being conveniently moved from one vehicle frame to another and in operation, substantially its entire weight may be supported upon the structure to which it is applied. The stamping device may be readily conditioned for applicatlon on pieces of work of different thicknesses by removing the demountable jaw 6 and replacing the-same by another j aw having a thickness which is adapted to retain the work in an embossing relation to the type during oscillation of the cam member 18.

Although but one specific embodiment of this invention has herein been shown and de scribed, it will be understood that various changes including the size, shape and arrangement of parts may be made witl'ioutdeparting from the spirit of my invention and it is not my intention to limit its scope other than by the terms of the appended claims.

I claim: 1

'1. An indicia stamping including a link member, a work supporting arm journaled 011 said member, a rocker arm journaled on said member having an arcuate face in related proximity to the end of said work supporting arm, an operating handle rigidly mounted on said rocker arm and type seated upon said arcuate face. p

2. An indicia stamping device including an oscillatable support, a member forming a pivo-t fo'rsaid support and a stationary abutment for engaging one side of a planular piece of work, means journaled on said support having an arcuate surface in related proximity tothe extremity of said Work abutting member and including a rigid operating handle, and embossing elements seated on said cam face and having rolling engagement with another side of 'said work. 7 v
